Of course it has. Blest and Donghe wouldn't be selling P2O machines if it didn't work. It's JBII's secret catalyst thats supposed to make the process profitable. It's a shame Islechem doesn't say a word about it. The numbers they released are consistent with what the Blest/Donghe machines are capable of off the shelf - JBII could have saved shareholder money getting that data straight from the manufacturer.
